解决U盘无法mount故障：“$MFTMirr does not match $MFT (record 0).”

操作系统：centos5

今天想用下U盘，mount的时候出现故障：

[wyw@personal ~]$ sudo mount /dev/sdb1 /mnt

$MFTMirr does not match $MFT (record 0).

Failed to mount '/dev/sdb1': Input/output error

NTFS is either inconsistent, or there is a hardware fault, or it's a

SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows

then reboot into Windows twice. The usage of the /f parameter is very

important! If the device is a SoftRAID/FakeRAID then first activate

it and mount a different device under the /dev/mapper/ directory, (e.g.

/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation

for more details.

开始考虑是不是有什么RAID服务没启，因为前段时间在搞系统优化，是不是把什么服务down了，检查了一下，也没发现什么。老路子，google大神，好不容易找到篇介绍http://www.code007.org/?p=241（墙太厚了，呵呵），字太小了，我把主要的说下吧。主要是利用ntfsprogs utility包里的工具ntfsfix修理一下，感觉应该是把类似链接号什么的修理好，不愿继续查了，懒，呵呵。
